Eagle-eyed Arlingtonians might have noticed that a Dominion Energy substation in the Ballston area is called, strangely enough, the Clarendon substation, while it’s vice versa for another substation down the street.
A substation is a part of an electrical grid that enables electricity to be transmitted at different voltages. Dominion Energy’s Ballston substation at 3241 Wilson Blvd is near Clarendon, just west of Northside Social.
